ACCORDION.

SPECIFICATION forming part of Letters Patent No. 364,609, dated June '7, 1887.

' Application illed February 8, 1887. Serial No. 226,946. (No model.)

To all whom, it may concern:

Be it known that 1, JOHN F. STRATTON, of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Accordion, of which the following is afull, clear, and exact description.

The object of my invention is to provide a new and improved accordion having an accompaniment of sublime harmony.

The invention consists of an additional set of bass-reeds tuned to a higher or lower pitch than the ordinary bass-reeds, but in harmony with the same.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is an inside plan view of the accompaniment of an accordion provided with my improvement. Fig.2 is a sectional plan View of the accompaniment-box. Fig. 3 is a side elevation of the accordion with the accompaniment part in section. Fig. 4 representsa piece of music which can only be played on an accordion provided with my improvement.

It is a well-known fact that the accompaniment of an accordion as now constructed when played produces a monotonous sound, on account of having only two chords, the dominant and the tonic. In order to vary and enlarge the accompaniment, so as to obviate the monotony of the accordion, I provide the latter with an extra set of reeds, tuned to either a higher or lower pitch than the bass-reeds as now used.

The accompaniment of the ordinary accordion consists of the two sets of bass-reeds A and B, producing, when played, the dominant and tonic chords. To these two sets of bass reeds A and B, I add another set of reeds, C, tuned to either a higher or lower pitch than the said bassreeds, but in full harmony with the same. This set of reeds O is either played separately or in connection with one of the two bassreeds A and B; or the three sets of reeds A, B, and 0 may be playedsimultaneously. The extra set of reeds O is placed alongside of the reeds A and B, and is provided with the usual finger key or knob, D, connected with key-valve by which the reed is sounded when the said finger-key D is pressed. E is the usual air-inlet valve of the accordion.

The diagram shown in Fig. 4 represents a piece of music which can be played with my improved accordion, but could not be performed by the accordions now in use, and it also illustrates the great variety of tones which can be produced with my improvement. The other parts of the accordion may be of any approved construction.

Having thus fully described my invention,

I claim as new and desireto secure by Let- I ters Patent- In an accordion, the combination, with the ordinary set of bass-reeds, of an additional set of bass-reeds operated independently from the said ordinary set of reeds, but being tuned to either ahigher orlower pitch than the ordinary bassreeds, but in full harmony with the same,

so as to produce sublime harmony in the accompaniment when the accordion is played,

substantially as set forth.
